Biological background
UBA1 (protein: T-cell surface glycoprotein CD3 zeta chain) is a commonly studied target in molecular and cellular biology. Functional context (as provided): Catalyzes the first step in ubiquitin conjugation to mark cellular proteins for degradation through the ubiquitin- proteasome system (PubMed:1606621, PubMed:1447181). Activates ubiquitin by first adenylating its C-terminal glycine residue with ATP, and thereafter linking this residue to the side chain of a cysteine residue in E1, yielding a ubiquitin-E1 thioester and free AMP (PubMed:1447181). Essential for the formation of radiation- induced foci, timely DNA repair and for response to replication stress. Promotes the recruitment of TP53BP1 and BRCA1 at DNA damage sites (PubMed:22456334). . Reported cellular localization context: Cytoplasm . Mitochondrion . Nucleus . Tissue expression notes (as provided): Detected in erythrocytes (at protein level). Ubiquitous. .
Research relevance and current trends
- Research context keywords from the source record include: Cell Biology,Epigenetics and Nuclear Signaling,Proteasome / Ubiquitin,Proteolysis/Ubiquitin,Ubiquitin & Ubiquitin Like Modifiers.
- Current studies often focus on connecting target abundance/localization to pathway perturbations across models, tissues, and cell states.
- Quantitative and multiplexed assays (e.g., imaging + immunoblot panels) are commonly used to compare phenotypes across conditions and time-courses.
Common research applications
- Western blotting (WB): assess relative target abundance across samples, treatments, or time-points.
- Immunohistochemistry (IHC): evaluate spatial distribution of target-positive staining in tissue architecture.
- Immunofluorescence/ICC (IF/ICC): visualize subcellular localization patterns and cell-to-cell heterogeneity.
- Flow cytometry: quantify target-positive populations and compare shifts in marker distributions.
Workflow ideas (metafield): Validate UBA1 antibody specificity using KO/KD control samples (WB/IF/IHC as appropriate), Detect UBA1 expression by Western blot in cell or tissue lysates, Detect UBA1 in FFPE tissue sections by immunohistochemistry, Localize UBA1 by immunofluorescence/immunocytochemistry in cultured cells, Quantify UBA1-positive cells by flow cytometry in single-cell suspensions
Notes for experimental interpretation
- Consider isoforms and post-translational modifications (PTMs) that may shift apparent molecular weight or epitope accessibility.
- Apparent molecular weight may vary by sample type and processing (observed MW: 118 kDa; calculated MW: 117849 MW).
- Control concepts: include appropriate negative controls (e.g., isotype, KO/KD samples) and orthogonal validation when feasible.
